Adsorption and Removal of Nitrogen and Phosphorus from Eutrophic Water by Straw Carbon and Aluminum Sulfate and Influencing Factors
In order to solve the problem of eutrophication in China, straw carbon and aluminum sulfate as an effective adsorbent used to absorption of total phosphorus and total nitrogen in water. Through the laboratory simulation test,by equilibrium adsorption method, the author investigated the effect on the adsorption under different environmental factors as the dosage of aluminum sulfate, pH, shaking time, temperature, disturbance, straw carbon size and so on. The results showed that with the dosage of aluminum sulfate and straw carbon was 0. 2 mg/L,the shock time was 120 min, the best adsorption of the removal rate could reach 80％ or more. Among different factors, aluminum sulfate and straw carbon the tatal phosphorus and nitrogen of adsorption analysis indicated that adding an appropriate amount of aluminum sulfate and straw carbon could reduce the total nitrogen and total phosphorus content in water, the adsorption on temperature, pH, shock time was sensitive. That was to provide a favorable basis for solving the problem of water environment in China.
